tolaims. i (C1. 23a-zo) l This invention aims to provide a guard rail of simple, design, which will be relativelyinexpensive to manufacture, but fully as strong and 'elficient as any of the types heretofore available. The guard rail of the invention and its mode of manufacture possesses suiiicient flexibility .to allow it to conform., as far asgeneral detailsand alignment are concerned, to various, steam railroad and street railway requirements. vOne object of the invention is to provide a guard rail of twoseparately formed parts, so that the guard rail proper can Vbe fabricated from material having agreater resistance to wear than the supportingpart of the guard structure. This is advantageous, for it provides a construction whereinthe Vpart. subjected to severest service can be made of relatively high grade material,

' such as high carbon heat treated steel orthe like andthe remainder of the structure can be made of variousgrades of low carbon steel or the like. Y

A further object of the invention is to provide a guard rail structure comprised of aV base portion having integrally formed chairs with recessed seats adapted to support with great rigidity a separately formed guard rail. Another more detailed object of the invention relates to the provision of a guard rail constituting two separately formed parts, one of which has a base portion adapted to support the running rail and integral chairs, the other of which constitutes the guard rail proper, which is notched for interlocking engagement with the chair portions of the base.

- The above and other features of the invention will be more fullyapparent from the following detailed disclosure when read in connection with the accompanying drawings, in which- Fig. 1 is a plan view showing my improved guard rail and a related running rail;

- Fig. 2 is a detail view in side elevation showing the guard rail structure alone;

Fig, 3 is anelevation viewed from the left end of Fig. 1;

Fig. 4 is a transverse vertical section on line 4--4 of Fig. 1;

Fig. 5 is a View illustrating a modication;

Fig. 6 is a perspective detail of the guard rail.

Referring in detail to the drawings, 1 designates the guard rail and 2 the supporting base therefor. This base is provided with upstanding chair portions, indicated generally by numeral 3. Each chair portion includes upwardly extending parts 4 and 5, which define the upright boundaries of recessed seats 6, in which the guard rail is adapted vto be fitted! On one'face,` the guard rail is formed with diverging notches 7, which are adapted for interenga'gement with the projections 5 of then chairs. On the opposite face, theV guard rail is formed with notches 8 into which theprojection l4 of `the chairs extend. Thenotches 8 are substantially parallel, whereas the notches l are other than parallel. `In Fig: 2, the notches 7 are shown` asconverging upwardly. Alternatively', these notches may be fforned to converge downwardly, as illustrated in the modication of Fig. 5. The extensions 4 andff of the chair portions, as formed in the process of manufacture, are all substantially parallel.,A At the time of assembly a heavypressrev is applied tothe guard rail, whichI results in bending the extensions to the diverging positions, such as show n in Figs. 2 and 5,"'thu'smechanically` inter-` locking-the notched guard 'rail 1 withl the chair portions. VIf desired, however, I also contemplate merely seating-the substantially rectangular guard rail within squared recesses 6 formed in the chair portions and then welding the guard rail `to the chair extensions 4 and 5. Or, in some cases, Iv may provide the interlocking notched varrangement above described and also Weld the guard rail to the chair portions at one or more points'.

The base 2 of the structure has a bearing portion 9, which extends laterally a sufficient distance to extend under the flanges 10 of the running rail 11. This base is provided with suitable spike holes l2 by means of which the same can be spiked to the usual railway ties.

At each end, the guard rail may be beveled as indicated at'13. Adjacent these beveled portions, the'end chair portions 14 may be bent over at an angle, Aas clearly indicated in Figs. 1 and 2.

The guard rail can be conveniently made of square or rectangular bar stock and it can be bent in plan to the shape indicated in Fig. 1, wherein it is noted that the intermediate portion is substantially or approximately parallel to the running rail 11, while the opposite ends vare flared away from the rail. The guard rail Such acomposite structure en- UNITED `.,TKFES PATENT, OFFICE l wheel flanges or other moving parts of the rolling stock. l

The base and chair portion of the guard rail structure herein described may be formed of relatively inexpensive low carbon steel. Usually, this part of the structure will be stamped out from at material and bent to final form on suitable presses, or the base and chair portions may be integrally formed by drop-forging. Or, alternatively, they may be otherwise forged. I also contemplate casting, the base and chair portions and securing the heat treated steel guard rail in place, by interlocking slotted parts or by welding.

'Ihe guard rail, instead of being made of highV carbon heat treated steel, may alternatively be made of wear-resisting alloy steels such as high manganese chrome nickel, steel, etc.

Instead of Vcutting or stamping out the flat stock toV form the base and chair portions, such stock can be fashioned by burning the same along suitable outlines byV an Oxy-acetylene torch. Such burning avoids the use of expensive dies which are necessary when the parts are stamped out. f

While I have described quite precisely the detailed structural Yfeatures ofthe embodiment of the invention herein illustrated it is not to be Y construed that I am limited-thereto since various modications and substitutions of equivalents may be made by those skilled in the art without departure from the Yinvention as deiined in the appended claims. Y WhatI claimvis:-

1. Arailway track adjunct comprising a base, a plurality of chairs forming an integral part thereof, each chair comprising two upwardly extending portions whoseY upper'- extremitiesconverge with respect to ,one another, seats formed in said converging extremities and a guard rail having a sidev wall with. converging notches 1 formed therewith for engagement with said upwardly extending extremities of the chairs.

. tween several adjacent ties, chair portions bent upwardly and extending laterally from said base, upwardly opening recessed seats in said chair portions, a guard-rail having substantially upright notches in interlocking engagement with the chair portions and end plates in alignment withand abutting the ends of the guard rail.

4. A railway track adjunct comprising a base, a plurality of chairs forming an integral part thereof,'each chair comprising two substantially upright converging portions, seats formed in said converging portions, a guard rail having a side wall with converging notches formed therein for interlocking engagement with said chair portions, said base having an upwardly bent portion in alignment with and abutting the end of the guard rail.

`5. A railway track adjunct comprising a base, a plurality of chairs forming an integral part thereof, each chair comprising two substantially upright converging portions, seats formed in said converging portions, a guard rail having a side wall withconverging notches formedftherein for interlocking engagement with the chair portions, said base having at one end thereof an obliquely bent v*portion and said guardrail having an oblique-portion in alignment and in abutting relationship therewith. c
